One Texas man pleaded guilty today, while a south Louisiana man and a Texas woman were sentenced in their roles in the same drug trafficking conspiracy.

U.S. Attorney Kenneth Polite says Kevin Gonzales, 25, of Houston, pleaded guilty to conspiracy to distribute and to possess with intent to distribute over one kilogram of heroin.

Also today, Reginald Washington, 33, of New Orleans and Martha Quinones, 51, of Houston, were sentenced after they pleaded guilty in the same investigation.

Investigators say all three defendants were involved in a heroin trafficking operation that involved Gonzales and Quinones traveling from Houston to New Orleans on a Megabus, then Washington distributing the heroin near the intersection of Loyola Avenue and Harmony Street in Central City.

Judge Carl Barbier sentenced Washington to 10 years in prison, followed by eight years of supervised released. Quinones will also spend 10 years in prison, followed by five years of supervised release.

Meanwhile, Gonzales faces anywhere from 10 years to life in prison for his role, as well as a possible fine of up to $10 million. His sentencing is scheduled for January 12.
